could not find doxygen (missing: doxygen_executable)
使用cmake ..
有时候会遇到如下问题：
<code class="javascript">$ cmake ..-- The CXX compiler identification is GNU 11.2.0-- Detecting CXX compiler ABI info-- Detecting CXX compiler ABI info - done-- Check for working CXX compiler: /usr/bin/c++ - skipped-- Detecting CXX compile features-- Detecting CXX compile features - done-- Looking for C++ include pthread.h-- Looking for C++ include pthread.h - found-- Performing Test CMAKE_HAVE_LIBC_PTHREAD-- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Success-- Found Threads: TRUE-- clang-tidy found: /usr/bin/clang-tidy-- Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE)Doxygen need to be installed to generate the doxygen documentation-- Configuring done-- Generating done</code>
安装doxygen即可。
例如ubuntu：
sudo apt install doxygen
然后：
什么是doxygen？ 从源代码生成文档 Doxygen 是从带注释的 C++ 源代码生成文档的事实上的标准工具，但它也支持其他流行的编程语言，例如 C、Objective-C、C#、PHP、Java、Python、IDL（Corba、Microsoft 和 UNO/OpenOffice 风格） )、Fortran，在某种程度上也支持D. Doxygen 也支持硬件描述语言VHDL。
Doxygen 可以通过三种方式实现：
它可以从一组文档源文件中生成在线文档浏览器（HTML）和/或离线参考手册（\mbox{\LaTeX}）。还支持在 RTF (MS-Word)、PostScript、超链接 PDF、压缩 HTML 和 Unix 手册页中生成输出。文档直接从源代码中提取，这使得文档与源代码保持一致变得更加容易。 可以配置 doxygen 以从未记录的源文件中提取代码结构。这对于在大型源代码分发中快速找到您的方式非常有用。 Doxygen 还可以通过包括依赖图、继承图和协作图的方式将各种元素之间的关系可视化，这些都是自动生成的。 还可以使用 doxygen 创建普通文档（就像我为 doxygen 用户手册和网站所做的那样）。 Doxygen 是在 Mac OS X 和 Linux 下开发的，但设置为高度便携。因此，它也可以在大多数其他 Unix 风格上运行。此外，还有适用于 Windows 的可执行文件。
